Myfsaid inventionrelates to a non-freezing device the pump may be so located as to pass v device for preventing freezing of the water through the instrument board with a knob on used/in the radiator of an automotive vethe'end of the plunger rod for operating it hicle, and it is an object thereof* to provide and the handles or handwheels of Valves y28 kmeans for removing the water from the radiand 29 may project through said instrument 55 ator to a non-freezing container, and return board above and below such knob. ingsuch water to the radiator when desired; The radiator has a cap 30 closing the usual K' e'ferring to the drawings, in which simifilling opening and an overflow pipe 31 is lar reference characters indicate similar here shown a'sextending out through the side y parts: n of the radiator, but obviously may be of any 60 lF ig. 1, is a side elevation of my device in suitable form and located in any conventional Working position, and l or desirable position.
